Description
AN ASSEMBLY, KIT AND INSTALLATION
FIELD OF THE PRESENT INVENTION [0001] The present invention relates to an assembly for mounting utility, such as but by no means limited to water mains, sewage piping, air conditioning ducting, electrical cabling and so forth. The assembly is adapted for mounting utilities in a ceiling cavity in a building between a false ceiling and flooring of a level above. The present invention also relates to a kit that can be added to pre-installed utilities, and a building in which the assembly or the kit has been installed.
BACKGROUND OF THE INVENTION [0002] Contemporary multi-level buildings typically have flooring in the form of suspended concrete slabs that are supported between posts or cantilevered. Non-load bearing internal walls are often erected on the floor and extend to a “false ceiling” comprising removable panels. Utilities, such as water mains, sewage, fire services, ducting for air conditioning, power cables and so forth are typically attached to an under face of the flooring in a ceiling cavity. Typically, threaded bars are used to support the utilities, and to comply with building regulations relating to seismic events, additional wire cables may be installed to provide lateral stability to the utilities in the ceiling cavity. The wire cables are typically oriented upwardly on opposite sides away from the conduits.
[0003] A difficult in adopting this approach is that sufficient space to accommodate the additional wire cables is not always available in the ceiling cavity. The present invention provides an alternative to the conventional wire cable installation.
SUMMARY OF THE PRESENT INVENTION [0004] An embodiment of the present invention relates to an assembly for mounting a utility in a building, the assembly including:
a locating member that is configured to engage the utility in an installed operative position;
a primary member having: i) a first end portion that is configured to connect to an underside of flooring of the building, and ii) a second end portion that is configured to support the locating member, wherein the primary member can be used to support the utility in an operative position under normal operating conditions; and

DETAILED DESCRIPTION [0067] A preferred embodiment of the present invention will now be described in the following text with reference to the accompanying figures. The text includes reference numerals to help identify the corresponding features in the figures. However, to maintain the clarity of the figures, all of the reference numerals have not been included in each figure.
[0068] Figures 1 and 4 illustrate bracing assemblies for mounting a utility in a ceiling cavity of the building. The assemblies include a locating member in the form a clamp 11 that engages and the utility (or utilities) in an installed operative position, a primary member 12 including a threaded rod 12a for connection to the clamp 11, and a bracing structure 13 having an elongated member 13a whose cross-section is C -shaped as shown in detail in Figure 3. The elongated member 13a has a rigid body. In the case of the assembly 10 in Figure 1, the primary member 12 and the bracing structure 13 are both connected to the clamp 11 and to an under-face of flooring 20 of the building. In one example, the under-face of the flooring 20 may be covered by a false ceiling. In other examples, the under-face of the flooring 20 may be exposed, in which case the under-face of the flooring forms a ceiling itself. In yet another example, it will be appreciated that there may be no level below the flooring. Moreover, the flooring may be substituted with any suitable structure, including beams, bearers, joists, lintels and trusses or any other part of a building.
[0069] In the case of the embodiment shown in Figure 1, the clamp 11 includes a Ushaped body having legs that can engage and straddle a utility. The utility is not shown in Figure 1. The U-shaped member comprises two halves, which in the orientation shown in Figure 1 defines an upper leg 14a and a lower leg 14b. The upper leg 14a and the lower leg 14b each have an attachment flange 15 that enables the upper Ieg14a and the lower leg 14b to move relative to each other to facilitate assembly of the clamp to the utilities, connection to the primary member 12,connection to the bracing structure 13. The upper Ieg14a and the lower leg 14b also have tabs having a hole for receiving a fastener, such as a nut and bolt, in a central location of the U-shaped formation. The lower leg 14b of the U-shaped body also includes a lower flange 16 that can receive a fastener such as a selftapping screw, or a nut and bolt fastener, for attaching the lower leg 14b to the elongate member 13.

Ideally the primary member 12 is a threaded rod 12a and two nuts can be fitted to the threaded bar either side of the opening in the yoke formation 17 to secure a lower end of the rod 12a to the yoke formation 17. The upper end of the threaded rod 12a may be fitted to a mortar bolt as desired for attachment to the underside of the flooring 20.
[0071] An outer end of the upper leg 14a may also be connected to the elongate member 13a of the bracing structure 13, via any suitable means. For example, a self-tapping screw or a nut and bolt fastener. Ideally however, the outer end of the upper leg 14a includes a head and neck formation 18 which can be received by a slot 19 in the bracing structure 13. To interconnect the outer end of the upper leg 14a, the head formation 18 is oriented such that the plane of the outer end aligns with the slot 19, i.e. the head formation 18 is oriented approximately 90° to its operative position and passed through the opening in the elongate member 13a, and then turned approximately 90° so that the shoulders of the head formation 18 can engage the slot 19 in the elongate member 13a.
[0072] As can best be seen in Figure 3, the elongate member 13a of the bracing structure 13 includes a line of spaced slots 19 along the length of the bracing structure 13 that face toward the U-shaped body to enable the U-shaped body to be secured to the bracing structure 13 at desired positions.
[0073] Afoot portion 21 is fixedly connected, and suitably by means of a high-strength weld, to an upper end of the elongated member 13a of the bracing structure 13.
[0074] Although the foot portion 21 may have any desired configuration, ideally, the foot portion 21 has a flat plate that can be located against a downwardly facing surface of the flooring 20. Fasteners such as mortar bolts 25 can be used to secure the foot portion 21 in a desired position.
[0075] The size of the U-shaped body, including the spacing between the legs 14a and 14b of the U-shaped body and the length of the legs 14a an 14b can be selected to conform to the size of the utility being supported.
[0076] Figure 1 illustrates a situation in which the fastener for securing the upper end of the threaded rod 12a extends through a foot portion 21 of the elongate member 13.
However, it will be appreciated that this is not required and that the anchor of the threaded rod 12a may be spaced from the foot portion 21 of the elongate portion 13a.

-112019213375 08 Aug 2019 [0077] Figure 4 illustrates another embodiment in which the utility is supported by the assembly 10 in a channel. The embodiment includes all the features of the embodiment illustrated in Figure 1, together with some additional features. Specifically, in the case of Figure 4, the assembly includes a pair of primary members 12 that include inner upright threaded rods 12a, a pair of bracing structures 13 that include outer elongate members 13a having a C-shaped cross-section, and a set of the clamps 11 having a U-shaped body. The assembly 10 also has a bridging member 22 that spans between the pairs of primary members 12 and the pairs of bracing structures 13.
[0078] Figure 6 is a perspective view of an elongated member 23 having spaced apart slots 19 that extend longitudinally along the elongate member 23. The elongate member 23 is representative of the bridging member 22 and the bracing structures 13. That is to say, the bridging member 22 and the bracing structure 13 can both have the same structure.
[0079] Figure 5 is a perspective view of the different sized clamps 11 shown in Figure 4, which have a left leg 26a and right leg 26b. The lower end of the left leg 26a and the right leg 26b includes a male formation including a head and neck formation 18. In use, the head portion can be aligned with the slots 19 of the bridging member 22, advanced through the slots 19, and then rotated approximately 90° such that the head portion engages the slot 19.
[0080] The U-shaped body are connected to suitable slots 19 of the bridging member 22, and attachment flanges 15 of the left leg 26a and of the right leg 26b can be connected using a fastener, suitably a nut and bolt fastener.
[0081] Opposite ends of the bridging member 22 are connected to the bracing structures 13 by right angled brackets 24 that are connected to the bridging member 22 and the elongate members 13 by suitable fasteners, preferably nut and bolts.
[0082] The upper end of the bracing structures 13 include a foot portion 21 having openings that can be located against and underneath face of the floor 20. The foot portion 21 include openings for receiving mortar fasteners. The foot portions 21 are fixedly connected to the bracing structures 13 by a high strength weld.
[0083] The lower end of the threaded rod 12a passes through an opening in the bridging member 22 and a nut is fixed to a lower end of the threaded rod 12a.
[0084] As can be seen in Figure 4, the bridging member 22 can be sized to allow multiple

-122019213375 08 Aug 2019 clamps 11 to be attached to the bridging member 22.
[0085] Figure 7 illustrates an unbraced assembly 30 including a clamp 31 and a threaded rod 32, in which an upper end of the threaded rod 32 is connected to an underneath face of the flooring 20 and a lower end is connected to the clamp 31.
[0086] To support conduits in a ceiling cavity in a manner to withstand foreseeable seismic activity, the bracing assembly 10 can be used in combination with an unbraced assembly 30 such as the unbraced assembly 30 shown in Figure 7. Depending on the spacing between the structure above the conduits, typically a downwardly facing surface of flooring, the conduits themselves, an installation in a building may includea combination of bracing assemblies and unbraced assemblies.
[0087] For example, when the conduit is supported up to 500 beneath a downwardly facing surface of the flooring, one or more unbraced assemblies may be positioned between the bracing assemblies.
[0088] Figure 8 is perspective view of an installation 34 comprising alternating bracing assemblies 10 and unbraced assemblies 30 supporting a length of piping 33. In other words, each bracing assembly 10 is separated by an unbraced assembly 30. However, it will be appreciated that an installation 34, may include two or more consecutive bracing assemblies 10 or two or more consecutive bracing assemblies 30 at one or more instances along the length of the piping 33.
[0089] Table 1 below describes various examples of installations comprising a combination of the bracing assemblies 10 and unbraced assemblies 30. For instance, example 1 is an installation comprising 100mm steel piping that is suspended 500mm beneath the under-face of flooring. It is recommended that an unbraced assembly 30, such as that shown in Figure 7, be spaced 1,200mm along the piping from the next unbraced assembly 30 ora bracing assembly 10, and that each bracing assembly 10, such as that shown in figure 1, be spaced by 6,000mm along the piping.
[0090] In the situation in which 100mm steel piping is suspended 1000mm beneath the under-face of flooring, it is recommended that an unbraced assembly 30, such as that shown in Figure 7, will be spaced by 1,200mm from the next unbraced assembly 30 or a bracing assembly 10, and that each bracing assembly 10 , such as that shown in Figure 1, be spaced by 3,600mm.
